SPECIFICATION forming part of Letters Patent No. 732,985, dated 3' 111$7, 1903.

Application filed September 3, 1902. Serial No.121,9'76. (No model.) 7

To all whom it may concern:

Beitknown that we, JAMES M. WILSON, Jr. and JOHN B. DALTON, ofGraysville, county of Catoosa, State of Georgia, have invented a new anduseful Improvement in Schedule and Train Calculating Machines, of whichthe following is a full, clear, and exact description, reference beingbad to the accompanying drawings, making part of this specification.

Our invention is an improved schedule and train calculating machineadapted for use in making schedules for railroads and for the assistanceof train-despatchers; and it consists in the novel construction andcombination of devices hereinafter fully set forth, and particularlypointed out in the appended claims.

In the accompanying drawings, which form part of this specification,Figure 1 is a side elevation of a schedule and train calculating machineembodying our invention. Fig. 2 is a detail sectional view showing themeans for operating the time and distance indicating mechanisms. Fig. 3is a detail sectional view taken on a plane indicated by the line a: soof Fig. 2. Fig. 4 is a detail view showing the connection between thehands and the arbor-s which carry them. Fig. 5 is a detail view of thedial of one of the distanceindicating mechanisms.

In the practical embodiment of our invention we construct a frame 1,which is preferably provided at its ends with supportinglegs 2. Thisframe comprises longitudinally and horizontally disposed upper and lowerplates 3 4, respectively, connected together at one end by a pair ofvertically-disposed corner-bars 5 6, the latter in rear of the former.These bars are speed-bars, and each is provided with a scale of miles,reversely numbered, the scale on the bar 5 running up and that on thebar 6 running down. Thedrawings, Fig. 1, show the distance-scales asrunning from 0 to 1OO; but in practice the said scales may be of anyextent and should preferably be'graduated to indicate theindividualmiles and subdivisions thereof-say to tenths or twelfths of a mile. Onthe front of the lower plate 4 is a time-scale 7, on which are markedthe hours of a day and which in practice are marked with divisions ofthe hours. A similar time-scale 8 is on the upper plate 3. Gog-racks 9are on the said plates and are coextensive in length with thetime-scales. An angle-bar 10 is disposed longitudinally of the frame, onthe front side thereof, at a suitable height above the lower plate4,-and its left-hand endis supported at a fixed point on a pivot 11. Theright-hand end of the front angle-bar is disposed to sweep on the scaleof the front distance-bar 5. The latter is here shown as provided with acurved slot 12, concentric with the pivot 11, and the angle-bar 10 isprovided with a suitable stop 13, here shown as a setscrew, working inthe slot 12, whereby the angle-bar may be seen red at any desired pointon the distance-bar 5. A rear angle-bar 14, which is similar to theangle-bar 10, is pivoted at its left end at 15. Said rear angle-bar isdisposed to sweep over and to coact with the rear distance scale-bar 6.

A vertically-disposed carriage 16 is adapted to travel longitudinally onthe frame 1. This carriage is provided with time indicating mechanisms AA and distance-indicating mechanismsB B. The former are operated by thecog-racks 9 and the latter by the respective angle-bars 14 10. Each timemechanism has a dial 17, and each distance mechanism has a dial 18. Thesaid dials are on the front side of the carriage. Each time mechanismhas hands 19 19, disposed to sweep on the time-dial. The hand 19 iscarried by an arbor 20, which has its hearings in the carriage and isprovided withaspur-gear 21, that meshes with one of the cog-racks 9. Thehand 19, which indicates the hours, is carried by a sleeve 20% whichrevolves on the arbor 20. The gear 21 is loose on the arbor 20, andapinion 21 is loose on the sleeve 20. A pair of gears differing indiameter and rotating in unison on a suitable support, which gears areindicated in dotted lines in the drawings, respectively engage the gears21 21*, whereby the latter is driven appropriately to turn thehour-hand. Hence when. the carriage is moved to the right the hands ofthe time mechanisms will be turned, and the position of the carriage onthe time-scales will be indicated by the position of the hands on thedials of the time mechanisms, as will be understood. A clutch sleeve ornut 20 is screwed on one end of the arbor 20. By loosening this sleeveor out the hands may be appropriately set without affecting the gearswhich operate them.

The dials of the distance-indicating mechanisms are numbered tocorrespond with the distance scale-bars, and each distance-indicatingmechanism has hands 22 22, which turn on its dial. Each hand 22 iscarried by an arbor 23, which may be revolved by a suitable train ofgears including an operatinggear 24, that is engaged by a rack-bar 25,which is slidably connected to and is adapted to be actuated by one ofthe angle bars. Each'rack-bar 25 is here shown as pivotally connected toa sleeve 25", slidable on one of the angle-bars, and as slidablyengaging one side of the carriage, as at 25", whereby it is kept inengagement with its gear 24 at all times. Each hand 22 is carried by asleeve 22", which revolves on the arbor 23. The latter and the sleeve 22arerespectively provided with a gear 23 and a pinion 22, engaged,respectively, by appropriate members of the train of gears in thedistance mechanism. The gear 23 and pinion 22 are loose on theirrespective arbor and sleeve, and a clutch sleeve or nut 26, similar tothe clutch sleeve or nut 2O hereinbefore described, is screwed on oneend ofthe arbor 23. By loosening this clutch sleeve or nut the hands ofthe distance mechanism may be appropriately set without affecting thegears which operate them. It will be understood that when the angle-barsare set angular-1y with relation to the plates 3 4; parallel with thepath of the carriage and the latter is moved to the right the distancemechanisms will be operated by the rack-bars 25 at a rate of speeddetermined by the angles of the angle-bars as indicated on the scales 56.

In the operation of the invention the anglebars are set appropriately onthe scales 5 6 to indicate the rate of speed at which the trains are torun, and the hands on the time-dials are set to indicate the time thetrains are to start. The hands on the distance-dials are set at O. Bythen moving the carriage to the right the dials will indicate the pointat which the trains will meet. For instance, as-

suming that the trains are one hundred miles apart, traveling towardeach other at the rate of forty miles per hour, and that they start attwelve oclock, both the angle-bars being at the same angle withreference to the respective plates 3 4 and the plane of movementof thecarriage, the respective distance-indicating mechanisms will operate atthe same rate of speed and their hands will indicate 5O on thedistance-dials when the hands on the time-dials indicate 1.15. Theangle-bars may be set appropriately for trains running at differentrates of speed either toward each other or one following the other, thetrain last started being the faster, and by appropriately operating themachine the same will indicate the point and time where the trains willmeet or when and where the slower train will be overtaken by the faster.Hence the utility of the machine for making the necessary calculationsfor railway timeschedules will be apparent.

We do not desire to limit ourselves to the peculiar construction andcombination of devices herein shown and described, as it will be evidentthat modifications may be made therein within the scope of the appendedclaims.

Having thus described our invention, we claim 1. In aschedule-calculating machine, the combination of a fixed distance-scale,with a movable carriage, a time-indicating mechanism,adistance-indicating mechanism, means, operated by the movement of thecarriage, to actuate the time-indicating mechanism, an angle-bar,adapted to be set on the fixed speedscale, and means, actuated by saidangle-bar, to operate the distance-indicating mechanism when thecarriage is moved, substantially as described.

2. In a schedule-calculating machine, the combination of a fixeddistance-scale, with a movable carriage, a time-indicating mechan ism, adistance-indicating mechanism, means operated by the movement of thecarriage to actuate the time-indicating mechanism, an angle-bar,adaptedto be set on the fixed speedscale, and a rack-and pinion mechanism,actuated by the angle-bar, to operate the distance-indicating mechanismwhen the carriage is moved, substantially as described.

In testimony whereof we have set our hands this 29th day of August, A.D. 1902, in the presence of two attesting witnesses.
